 ### Fixes
 
+- The Claude Code plugin root is now `skills/` instead of the repository root, so installing `pascal-agent-skills@pascal` copies the two skill bundles and their MCP configuration instead of caching the whole monorepo and running `bun install` against the root lockfile ([#832](https://github.com/pascalorg/editor/pull/832))
 - Preserve custom scene materials across save, load, clone, fork, and live sync. Materials were dropped at every persistence boundary, so a scene reopened with default surfaces. Collections were dropped on MCP import for the same reason ([#597](https://github.com/pascalorg/editor/pull/597)) by [@ShiroKSH](https://github.com/ShiroKSH)
 - Wall junction mitering is now deterministic for exactly-collinear walls, so identical scenes produce identical geometry regardless of node iteration order ([#596](https://github.com/pascalorg/editor/pull/596)) by [@tomatotomata](https://github.com/tomatotomata)

This local connector needs no Pascal account or API key and does not upload projects automatically. Its plugin root is this repository's `skills/` directory, so an install copies only the skill bundles and their plugin metadata rather than the repository.

 Claude Code 2.1.258 loads both the user-scoped `pascal` server created by `pascal mcp setup claude` and the plugin-provided server. Run `claude mcp remove --scope user pascal` before reloading or restarting Claude Code so only the plugin owns the connection lifecycle. Use `/mcp` to remove or disable any project- or local-scoped Pascal connection too. Leaving both connections active violates the one-active-agent-client-per-local-service requirement. For a hosted Pascal project, disable the plugin-provided local server in `/mcp`, then configure the hosted endpoint from the setup reference.
 
 Plugin installation alone never creates an account, uploads a project, or authorizes paid work.
 
-The root [`plugin.json`](../plugin.json) is the portable Agent Plugins manifest used for OpenAI submission, and the root [`mcp.json`](../mcp.json) is the only MCP configuration path Codex and Cursor read; Claude Code reads the same server from `.mcp.json`. The repository keeps `.codex-plugin/plugin.json` as a compatibility fallback and validates that both expose the same OpenAI listing metadata. Public-directory submission, review, and publication are separate external steps; a Git marketplace install does not make the plugin publicly listed in ChatGPT or Codex.
